摘要

Abstract

The adsorption/desorption of phosphorus across the sediment-water interface is the main mechanism that controls the buffering capacity of DRP in coastal and estuarine water. Determination by three processes revealed that: 1) DRP flux from early diagenesis in surface sediment isF p Dia =31.9μg/(m2·d)

which is only 1/1600 of the ammonia released; 2) at normal temperature and in the long term

the TDP released by adsorption/desorption across the sediment-water interface is a function of the major environmental factors; and 3) based on the determined SODR and assumed average water depthH(m) and residence timet R (d)

the maximum flux of DRP can be estimated.
